KEMA 94.5?

An STA for the heat? Stations I worked had AC at the transmitter building and if it went down the AC repair truck was there in an hour or two and the engineer had a temporary fix.

In hot climates like Puerto Rico where the humidity was often over 80%, I generally installed two units, each barely capable of cooling a site while together just coasting along, but allowing for backup if one went out. There are even controllers made for such installations so the two units don't fight with each other. They are commonly used in paces like laboratories or research facilities where loss of cooling or heating will destroy the work done so far.

During heat waves, getting AC repair can take days. I had a thermostat issue with one home unit, with outdoor temperatures in my courtyard being around 122°, and was told we could get service 6 days later.

That's how I equipped my transmitter sites in Florida. Two thermostats, one for each A/C unit. One thermostat was set a few degrees higher than the other. We monitored the indoor temperature at the transmitter sites. If the temperature went up a few degrees, we knew that we had an issue with one of the A/C units.

Talking about a lead-lag controller. Pretty common in prefab communications shelters for cellular / 2 way / broadcast. One AC unit is the "lead" unit. If the building temperature goes above a pre-set level, the second (or "lag") unit kicks in to pick up the heat load. You can also program them to swap which unit is the "lead" unit on a weekly schedule to even out the overall run time.

They're probably reading these forums...

Let's hope they get it back on full-power soon, and keep it there... Heck maybe they can work something out with Alpha Media's 94.5 in SA to rebroadcast each other and make 1 super-coverage station LOL.

Another "transmitter broke" STA from Roy. Many many of them for all his stations.

wasnt signed by roy.. im guessing his son.... kinda interesting. i think roy usually signs and files these himself

I knew this had to have a name in English. Since I did all those installs in places like Ecuador, Puerto Rico, the Dominican Republic and Miami, everything was discussed in Spanish (and, yes, in Miami I never recall doing business in English).

One of the reasons to do this in more remote locations or places where repair items may not always be in stock, having dual reliable A/C systems was intelligent and not very expensive. I never did it, but some stations had two generator sets as well.

KSKO 870 had two generators at some point

Maybe he's passed on some of the work to others, my guess... Hopefully Roy's doing well.

Very interesting discussion on how the AC units work at transmitter sites. But KEMA has a CP to move closer to San Antonio so maybe they'll not use the current site again at all?

I still don't see anything that was filed with KEON being off and now at reduced power.

At most of the stations where I've worked, standard policy was that we'd check the temperature in the transmitter building when we checked meter readings. Having said that, most every time I mentioned the transmitter room temperature was looking hot, nothing was done.

One of the stations where I worked allowed the NWS to use our building and tower. As soon as that other transmitter was put in, the transmitter shack routinely read over 90 degrees.

I had an LPB, Inc 5kw AM transmitter survive 120 degrees+ in a FL space coast transmitter room and keep on chugging

Not something I'd be bragging about if it were one of my sites.

This was back in.... 2005. I can only do so much, reported it to them.....I dont recall what the end result was, the AC failed.. but the company didnt show too much concern as I recall.
